GATE.

Application filed August 22, 1919.

To all whom t may concern Be it known that I, JAMES H. BURKE, a citizen of' the United States, 'residing at Rossmoyne, in the county of Hamilton and State of Ohio, h-ave invented certain new and useful Improvements in Gates, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved gate,whi`ch may be particularly adapted for use as an elevatory shaft gate or adapted as a farm or garden gate.

One of thev objects of the invention is to provide a gate of this kind comprising a pair of gate sections, which may be open by collapsing them upwardly and laterally toward and adjacent the opposite gate posts, to permit of a passage through the gate Opening.

A further object of the invention is`the provision of means for assisting materially in opening'the gate sections, when first having been started on their opening operations.

A further object of the invention is the provision of means for starting the gate sections on their opening-operations.

A further object of the invention is the provision of means for holding the gate sections closed, which means comprises a toggle link brace connecting between parts of one of thegate sections, to hold one gate section closed or down, and which gate section includes additional means to overlie a part of Y the other gate section, whereby it is held down in a closed position.

rlhe invention further aims to provide a gate of this character which is simple, efficient and practical in construction and may be manufactured for a relatively low cost and sold atv a reasonable profit.

The invention further aims: to1 provide a gate section comprisinga plurality of vertically arranged collapsibleslats, supporting- Specification of Letters Patent.

means carried on the gate sections, to prevent persons from leaning over the gate and looking up or down the elevator shaft.

Nh/ile the design and construction at present set forth and illustrated is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invent-ion comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings,

Figure l is a view in perspective, showing the Vimproved gate constructed in accordance with the invention, showing the gate closed.

Fig. 2 is a vertical sectional view through the gate posts, one of which is hollow or in the form of a boxing, the other constituting an upright, and illustrating the gate sections in elevation a-nd in open positions, illustrating the means for raising or opening the gate sections.

Fig. 3, is a horizontal sectional view on line. 3 8 of Fig. l, at a point immediately above the gate sections, thereby more clearly showing the detail construction.

Fig. AI is a view showing one of the gate sec-tions in elevation and its posts in section. to show the electrica-l means for operating the gate sections andV showing a part of the other section, so as to i-llustrate how it is held down: by the holding means of one of the gate sections.

Fig: 5 is a view inr elevation of one of the posts showing one ofthe gate sections col-- lapsed thereagainst.

Referring more' especially to the drawings, 1 and 21 designate the gate posts, and the post 1 isin the formy of a sin le upright as shown, and. has j ournaled in. forks in its upper end a pulley 3. Secured. to the side of the upright or post` l is a cushioning member 4C, which; may be constructed of rubber, thoughnot necessarily, for any other suitable material'V may beused, so as tocushion the gate section when itis rC ised. The upriglit or post 1- at a point substantially midway its upper and lower ends is pro videdl with an opening 5, in which a casting Gis fixed or secured, as shown at T. A pul- SecuredV at 12 pulley 14 is journaled. The upper end of the housing or'boXi'ng 11 is closed'as shown,

However, these upper Y and' lower bars'arec'onstructed zigzag, sov as )to provide horizontal parallel portions 23,

When the circuit is closed the solenoid is energized, thereby drawing the core thereinto, thereby creating a pulling action on the cables 0i and 43, thereby collapsing the gate sections. However, before actuating the push button 5l, the links 33 and 35 are collapsed outwardly.

The gate sections are provided with additional brace bars 5,8, which are so disposed, as to prevent persons from leaning over the gate, and looking up or down the elevator shaft, when the gate is employed for use in connection with elevator shafts. This brace 53 is reinforced by the brace 54, which extends downwardly from the brace 53 to the lower part of the gate, and is secured as at 55 to the gate section. It is an object of this invention to employ the gate for use in connection with elevator shafts and when so used, it is the aim to electrically operate the gate sections.

The lower portions of the adjacent ends of the gate sections are provided with cushioning members 3l to cushion the gate sections when lowered.

'I`he invention having been set forth, what is claimed as new and useful is:

l. In a gate, the combination with gate posts, of a pair of collapsible gate sections pivotally mounted upon said gate posts, and adapted when collapsed, to lie against the adjacent faces of the posts, means carried l i by one of the gate sections to hold it closed or extended downward, and means carried by one of the gate sections to overlie the other gate section, to hold the two sections closed` 2. In a gate of the kind set forth, the combination with a pair of gate posts, of a pair of collapsible gate sections pivotally mounted upon the adjacent faces of the posts, and adapted when collapsed, to lie flat against the adjacent faces of the posts, toggle link connections between the parts of one of the gate sections and the stationary part of the gate section to hold the gate section in its downward or extended position, and a device carried by one of the gate sections to overlie the other gate section, to

hold the two sections extended downward in closed positions.

8. In a gate as set forth, the combination with a pair of gate posts, of a pair of collapsible gate sections pivotally mounted upon the adjacent faces of the posts, and adapted, when collapsed, to lie against the adjacent faces of the posts, and means mounted on one of the posts and having connections with said gate sections for opening the gate sections in collapsed positions in contact with the adjacent faces of the posts.

el. In a gate, the combination with a pair of gate posts, of a pair of collapsible gate sections pivotally mounted upon the adjacent faces of the posts, adapted when collapsed, to lie against the adjacent faces of the posts, means for locking the gate sections in extended downward closed positions, means automatically collapsing the gate sections when the locking means is released, and means cooperating with parts of the gate sections to start them on their downward movement, said means for raising the gate sections comprising a solenoid including a core, and connections between the core and the gate sections for raising the same, when the solenoid is energized, and an electric circuit including the solenoid and the core, whereby when it is closed, the solenoid is energized and the core is dra-wn thereinto.

In a gate, a gate post, of a collapsible gate section pivotally mounted upon the gate post, said gate section comprising upper and lower bars having zigzag parts pivotally yconnected to the post, brace bars for the rst bars and having their outer ends connected to the rst bars and their inner ends pivoted to the post, the pivots of both sets of bars respectively being axially alined, whereby as the gafte section is tilted upwardly the bars will lie flat against the post, and vertical slats connecting the upper and lower zigzag bars and adaptedto lie flat against the posts when the sections co1- lapse.

In testimony whereof I hereunto aiiix my signature.
